How Come Uncertainty
A photon is comprised of two points of electric and magnetic saturation surrounded by fields of electric and magnetic force. The fields drive the points through space and determine their trajectory. Interaction happens near the points but need not happen at the points.
The electromagnetic fields that comprise a photon are in a state of constant change. This change drives the central point of a photon forward through space. We measure the photon's path to be that of the central point, but the fields exist spatially around the photon at an amplitude that is greatest close to the point and diminishes as the square of distance away from the point.
When this photon nears its target, churning electrons belonging to atoms in the target begin to sense the photon's approach. Some electromagnetic fields in the electrons will be in good phase relation with the approaching photon. Among this huge jumble of moving electrons, some will be more inclined to absorb the photon's fields than others. Those most inclined will probably not be dead center in the photon's path.
The process of an electron absorbing the fields of a photon, causes the fields to become unsymmetrical, being partially absorbed near the electron but in full force at a distance from the electron. This asymmetry drives the photon's point toward the absorbing electron, changing the photon's path at the last instant.
Electrons targeted to strike a point behave in a similar fashion. They are also comprised of electromagnetic fields and respond to the fields of other electrons. When they impact a target atoms in the target may be inclined to absorb or reject the electron depending upon the state of individual atoms. Those most inclined to accept the electron will probably not be dead center in the electron's path. This causes the electron's path to change at the last instant.
So, even though we can know the paths of things with great precision, it is not likely that we'll ever be able to predict exactly their impact points. But with this insight, there is a possibility that we might devise a more precise prediction. If we controlled the state of the target atoms so that they were inclined to absorb electrons, approaching electrons would be deflected less and we could better know the point of impact.
